The PW504 (Model: PW504) is a high-reliability power supply module engineered specifically for Yokogawa’s CENTUM VP and CENTUM CS 3000 Distributed Control Systems (DCS). This unit acts as the primary power interface for system racks, converting wide-range AC input into the stable, regulated DC voltage required by control processors, communication modules, and I/O subsystems.
Designed to operate in mission-critical industrial environments, the PW504 (Part Number: PW504) features advanced protection circuitry against voltage surges, overloads, and short circuits. It is typically deployed in dual-redundant configurations within the system backplane; if one power unit fails, the partner module instantly carries the full load without any interruption to the control process. This seamless failover capability ensures continuous plant operation and protects the integrity of real-time process data.
The PW504 (Model: PW504) provides a rugged power foundation for Yokogawa's most demanding control architectures.
